River in Washington, United States
The Copalis River is a stream on the Olympic Peninsula in the U.S. state of Washington. It originates in the foothills on the southwest side of the Olympic Mountains and empties into the Pacific Ocean.[2] The name "Copalis" comes from the Quinault language term /k'ʷpíls/.[5] The Copalises are a Native American group. Both the Chehalis people and Quinault Indian Nation claim the Copalis are a subdivision of their tribe.[6]
